The goal of the Generic Eclipse Modeling System (GEMS) is to bridge the gap
between the communities experienced with visual metamodeling tools, such as
the Generic Modeling Environment (GME), and those built around the Eclipse
modeling technologies, such as the Eclipse Modeling Framework (EMF) and
Graphical Modeling Framework (GMF). GEMS is being developed by the
Distributed Object Computing (DOC) Group at Vanderbilt University's
Institute for Software Integrated Systems (ISIS) and other collaborators,
such as Siemens Corporate Technology. GEMS is an open project and encourages
developers to extend, enhance, and use its tools. GEMS has been developed in
conjunction with research work done in collaboration with Siemens, IBM, and
PrismTech. GEMS is an open source project, based on the Eclipse License.

We are very happy to have a place where the GME community and the EMF
community can exchange not only experience but also artefacts and tools. By
providing a bridge between these communities, GEMS is going to have a strong
impact on the development of advanced model engineering techniques.
